SPECIFICATION forming-.part of Letters Patent No. 647,421, dated April 10, 1900.

Application filed August 3, 1899.

To all whom it may concern:

Be it known that I, EDWARD J. MALLEN, of the city of New York, borough of `Manhattan, in the county and VState of New York, have invented a new and Improved Hot-Air Register, of which the following is a full, clear, and exact description.

One object of my invention is to provide a hot-air register in which the slats are constructed of sheet metal arranged to overlap, so as to produce a smoke-tight connection, and to provive a frame also made of metal, the braces for the frame constituting means for the attachment of a cover or frontispiece.

Another object of the invention is to so construct the slats that their trunnious will be integral with the body of the slats and the bearings for the shifting devices for the slats also integral with said slats.

A further object of the invention is to s'o brace the several parts of the sheet-metal body that it will have practicallythe rigidity of a cast-metal body.

The invention consists in the novel construction and combination of4 the several. parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a plan View of'the improved register, the cover or front having been removed.A Fig. 2 is a transverse section taken substantially on the line 2 2 of Fig. 1 looking in the direction of the arrow a. Fig. 3 is a similar section taken on the line 3 3 in Fig. 1 looking in the direction of the arrowb. Fig. 4 is a perspective View of a corner-section of the device; and Fig. 5 is a perspective View' of a portion of one of the slats, the said view being on a larger scale than the other views.

The frame or bodyAoi the register is constructed of sheet metal and is of box-like or rectangular form, although its shape may be varied. The said body A vis provided with a reduced base-section a, and said reduced section is provided at its bottom with an o utwardly-extending flange 12, a similar flange l2a being formed at the upper or outer edge of the said body A. The sides of the said body are designated by the numeral 10 and Serial No. 725,995. (No model.)

the end portions by the numeral l1, and at upper flanges 12 where the side sections of the flanges connect with the end sections, the side sectionsjof the angesare provided with an upwardly-turned end 14, extending over the end flanges, as illustrated in Fig. 4, while the end iianges of the body are provided with downwardly-turned members 15, that extend over and engage with the side portions of said iianges, as is also shown in Fig. 4. The same connection between the ends and sides of the body is provided forthe contracted base portion a, in which, as shown in Fig. 4, the side l sections of the lower iianges 12 are bent over the end sections of said iianges, as shown at 1 6 in` Fig. 4, and the terminals of the end portions of the flanges 12 are carried over the side portions of said flanges, as shown at 17 in Fig. 4. The return ends of the various flanges l2 and 12a are clamped together in any suit able or approved manner.

The corners of the body are connected and braced by means of angle-irons 18, riveted to the sides and end portions of the body above the contracted section a thereof, and at the top of each angle connecting-iron 18 an aperture 19 is formed, so that the coveror frontispiece 2O maybe attached to the body by passing screws 21 through the said cover and frontispieceand into the apertures 19 in the angle-irons. Thus it will be observed that the body, although constructed entirely of sheet metal, will be as strong as a body of cast metal and very much lighter and more economic in manufacture.

A series of slats B is carried by the body A.

These slats are formed from sheet metal and l are preferably provided with an upset central longitudinal rib 19a, and the ends of the slats B are narrower than their body portions and are bent upward at a right angle to said body portions, forming end members or flanges 18a.

An opening 20 is made in each of the upturned end members 18, and the material obtained by forming the said opening 20 is bent upon itself and carried horizontally outward in longitudinal alinement with the cen- IOO 2 fltgliei tral upset rib 19a to form trunnions 2l, as is particularly show-n in Fig. 5. rThe-central slats B are provided at each longitudinal edge tained; but in the slats B, located at the sides of the body, the valley b is omitted at the outer edges of said outermost slats, as shown in Figs. 2 and 3, the outer edge ofl one of the outermost slats B` having a downwardly-extending flange 24, adapted to engage with the reduced or base portion a of the body at a point below the rib 13, whereas the opposing outermost slat B at its outer edge is provided with an outwardly-extendin g fiange 23, `adapted to engage with the reduced portion a ofthe body Aat a point above the side ribr13, adjacent to said uppermost slat, as isalso shown in Figs. 2 and 3;k but the valley b is formed at the inner edge of each of the said outermost slats B, so that all of the slats when closedV will have an interlocking dust and smoke proof connection with each other.

The trunnions 2la of the slats are journaled in the reduced or base portions a, of the body A, suitable washers 25 being provided,

and a shifting bar 27 is mounted to slide* atV the inner face of each end portion of the body A. l The said shift-ing bars are provided with pins 26, that pivotally connect with the up.- turned ends 18a of the slats B; but one of the shifting bars 27 is provided with notches29 'in its upper edge, as shown in Fig. 3, while the other shifting bar is provided with a handle 28, thaty extends out through the frontispiece of the register, and by'means ofV this handle the shifting bars are moved'endwise in the register.

The notches 29 in one of the shifting barsl 27 are adapted to receive the free endl of a spring 30, the said free end being preferably cylindrical, and the opposite end of this spring is attached to an end of the register, as shownv at 31 in Fig. 3, while a stud 32 has bearing upon the upper or outer surface of the spring between its ends, serving'to hold the free end of the spring in engagement with the shifting bar'with which it is to contact. Thus it Will be observed that by moving the shifting bars through the medium of the handle 28 the shifting barsmay be retainedin such po!v sition that the slats maybe fully or partially opened, or the 'shifting bars may be so moved as to effectually close the slats, as shown in Fig. 2.

Thevalleys, grooves, and lianges at the'lon-v gitudinal edges of the slats not only serve to produce a perfect interlocking engagement lbetween the slats, but likewise tend to materially strengthen the slats and enable very thin material to be successfully employed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a register, a frame having sheet-metal sides and ends, each formedwith a top and bottom liange, the top flanges being overflapped and bent around each other at the cor-v ners into'interlocking engagement, and the bottom iianges being also overlapped and bent around each other at the corners, as set forth.

2. In a register, a frame having sheet-metal sides and ends each formed with an outwardly= turned top andl bottom llange, the top and bottom flanges on the sides of the frame be ing bent at the corners up overthe top and bottom flanges on the ends of the'frame, and said latter flanges being bent down at the cor; ners over the anges on the sides of the frame, as set` forth.

3. In aregister, a frame having sheetmetal sides and ends, each formed with a reduced portion near its bottom and with a top and bottom flange, which {ianges are bent around each other at the corners into interlocking engagement, the sides of the frame being further formed with inturned horizontal ribs in their reduced portions, as set forth.

4. In a register, a slat constructed of sheet metal formed with a longitudinal rib, upturned ends, andan opening in each upturned end, the metal obtained by forming such openings forming trunnions for the slat, as set forth.

EDWARD J. MALLEN.
